Dustin Pedroia's (pictured) seventh inning grand slam powered the Red Sox to a 6-4 win over the Tampa Bay Rays at Tropicana Field Saturday night. The victory, Boston's tenth in a row, clinched at least a Wild Card playoff spot and lowered the Magic Number to clinch the division to three.

Rick Porcello went 6.1 innings for his 22nd win of the year. He allowed three Tampa Bay runs on eight hits and one walk while striking out nine.

Brock Holt gave Boston a 1-0 lead in the first with an RBI double that drove in Mookie Betts. The Rays countered with three runs in the third off Porcello, with the big blow being a two-run double by Brad Miller.

The Red Sox scratched another run across in the fourth on a run-scoring single by Hanley Ramirez.

Pedroia's grand slam came on a 2-2 count with two out in the top of the seventh. It was his fourteenth home run of the year and his fourth career grand slam.

Craig Kimbrel recorded his 30th save of the year despite giving up a solo home run in the ninth.
